They had a personal knowledge about Jesus, and were curious about the things that happened in Jerusalem those days.
( we all have personal interest in Jesus)

( we have read the scripture and experienced the divine touch of it at least in the minimum)
But they could experience Jesus only at the table when he broke the bread.
( But all these individual interest and knowledge of the scripture is not enough..., one should dare to be incorporated to the body of Mystical Christ, The church.
Experience him in the Eucharist. )
Christ experience = Personal search + Holy Scripture + Holy Eucharist
( if you miss anyone, dare to incorporate it quick……no shortcuts to grace.)
